i had to replace my head gaskets, while doing so I broke the cooling switch sensor, and the boot that connected it. I bought a new switch, and now the fan isnt kicking on when the car gets hot. The fan will turn on though when i turn on the a/c. Checked all the fuses, replaced the fan motor, and thermostat. I am running out of options. Any help will be greatly appriciated.
Thanks.

 

If you are talking of the fan switch it grounds the circut when the temperature reaches a preset point. Perhaps you missed a connection somewhere?

 

Sounds like a bad fan relay... Its location is next to your matser cylinder looks like a small black box. there is more than one relay in that area, I believe it's on the driver side.

 

If it is the relay isn't that located on the passenger's side of the radiator? I see two locations for it, the one CONVZ28 mentioned and the one I mentioned maybe someone can straighten it out.

 

thank you for the help gonna go check the fan relay next to the clutch master cylinder 1st since its the oldest. thanks again!!

 

I don't know what I was thinking but CONV Z28 is right.

 

mine was doing the same thing until i got a ac delco switch instead of the wells brand .when the it got to 200 the fan kicked on

 

The my auto parts dealer gave me was a standard ts 147
I beleive. but it turns on at 220 + this may be a secondary switch for a tpi set up. Can some one tell me what the propper part # is for the correct fan switch is. Mine use to kick on a 210 about and shut off at 190 or 180 it doesn't even come on now
I have to leave the ac on all the time.......
